Low Temperatures and Cryogenic Engineering Department

Do you think that LTCE page is dead? Or may be LTCE Dept. is dead? We regret to say that we are still alive. The reason for keeping silence for one year is simple. We started several new projects and therefore was forced to work hard to show that granting bodies are not wasting their money. No time for Facebook – can you imagine? And now we are back!
First thing is our recent paper in Scientific Rеports

Again it is mysterious cerium hexaboride, which plays a role of a liquid crystal.

In mean time, we would like to remember some interesting conferences in the field of strongly correlated electron systems, which have been held in Russia during 2017 with important contributions of LTCE staff and students. See our publications below and have fun!

Electron nematic effect induced by magnetic field in antiferroquadrupole phase of CeB 6 Article

International Workshop on Dzyaloshinskii-Moriya Interaction and Exotic Spin Structures (DMI 2017), which took place in Peterhof, Russia on May 23 – 26, 2017. Leading experts in the field are coming to one of the most beautiful places in the north-west of my country. This event is concentrated on chiral science. Several invited, oral talks and posters were presented.

The Moscow International Symposium on Magnetism (MISM) is being held at Moscow State University every three years starting with the year 1999. This year meeting happened on July 1-5. MISM is really enormously huge and brings together all aspects of modern magnetism together. We are proud to have several invited talks at this important international event.

Lebeldev Physical Institute of RAS and High Pressure Physics Institute of RAS has organized XIV workshop for young scientists “Problems of solid state physics and high pressure physics” with a topical title “Ideas and methods of condensed matter physics” (September, 14-24, 2017). This conference is traditionally organized at the Black Sea cost in the Sochi city, known by recent Winter Olimpic Games. Actually, the conference place is about 90 km from the city center (Sochi is really big!), which allows young physicists and lecturers to have a lot of fun.

Fantastic event is organized in a beautiful city of Kazan by Zavoisky Physical-Technical Institute of the Russian Academy of Sciences, the Academy of Sciences of the Republic of Tatarstan and the Kazan Federal University. This is Zavoisky Week (September, 25-29, 2017), which includes the annual International Conference “Modern Development of Magnetic Resonance 2017”, the Zavoisky Award 2017 ceremony and a special session devoted to the 110 anniversary of E.K. Zavoisky. By the way, E.K. Zavoisky is a person, who discovered electron paramagnetic resonance anf therefore give a future job for many scientists, including some working in our lab. On the photos you may find Zavoisky portrait and a replica of his original installation at which the first EPR signal was observed.

Dear Colleagues,

Season’s greetings and all good wishes for coming 2017!
Let the New Year will bring success and fulfillment of your desires.
Stay with our page in the New Year. Physics is fun!

With best regards,
LTCE Dept. Head,

Sergey Demishev

http://phys.org/news/2016-12-cerium-hexaboride-physicists-theory.html

Cerium hexaboride challenges physicists to develop new theory Scientists from MIPT and other research institutes and universities have discovered unusual phenomena occurring in a single cerium hexaboride (CeB6) crystal. By performing an electron spin resonance (ESR) experiment, the researchers confirmed the status of the material, which has been dubbed an "exc...

Ask our students, and they will answer that physics is an entangled story. But it is even more entangled than we can guess. Look at archetypical dense Kondo system with orbital ordering, cerium hexaboride, CeB6. After 40 years old history of successful implementation of strongly correlated mainstream view, ESR study of CeB6 shows both remarkable failure of existing theories together with violation of common sense. Last hope is likely accounting for spin fluctuations and itinerant aspects of magnetism.

Magnetic resonance anisotropy in CeB6: an entangled state of the art Electron spin resonance (ESR) in strongly correlated metals is an exciting phenomenon, as strong spin fluctuations in this class of materials broaden extremely the absorption line below the detection limit.

PHYS-USP, 2016, 59 (6), 559–563 It is shown that the - magnetic phase diagram of substitutional solid solutions exhibits two quantum critical points: , which corresponds to the disappearance of long-range spiral magnetic order, and , which marks the suppression of the phase with short-range magnetic order. It is established that t...

Кто сказал, что ученые сидят в своей высокой башне и не общаются с простым народом? Не только общаемся, но и говорим, что творится с российской наукой благодаря усилиям «реформаторов». В общем, нас цитируют.

Common wisdom tells that spin system orders in the strong magnetic field leading to a ferromagnetic ground state. However, recent study of magnetization in Mn1-xFexSi system up to 50 T shows that the magnetic field may induce “freezing” of the spins in disordered state.
