Heavy Fermion Physics
This article is intended to be a very brief review on the most basic facts and concepts of heavy fermion physics. A general overview is given as an introduction. In the following part, the mechanism leading to the formation of heavy fermions is explained briefly, and its connection to Kondo effect is emphasized. Then we talk about heavy fermion theories in more detail, where the concepts like K...
متن کاملHeavy fermion quantum criticality.
During the last few years, investigations of rare-earth materials have made clear that heavy fermion quantum criticality exhibits novel physics not fully understood. In this work, we write for the first time the effective action describing the low energy physics of the system. The f fermions are replaced by a dynamical scalar field whose nonzero expected value corresponds to the heavy fermion p...
متن کاملQuantum criticality in the cubic heavy-fermion system CeIn3-xSnx.
We report a comprehensive study of CeIn3-xSnx (0.55<or=x< or=0.8) single crystals close to the antiferromagnetic quantum-critical point (QCP) at xc approximately 0.37 by means of the low-temperature thermal expansion and Grüneisen parameter. This system represents the first example for a cubic heavy fermion in which TN can be suppressed continuously down to T=0. A characteristic sign change of ...
متن کاملProximity effects in the superconductor / heavy - fermion bilayer system
– We have investigated the proximity effect between a superconductor (Nb) and a “heavy-fermion” system (CeCu6) by measuring critical temperatures Tc and parallel critical fields H ‖ c2(T ) of Nb films with varying thickness deposited on 75 nm thick films of CeCu6, and comparing the results with the behavior of similar films deposited on the normal metal Cu. For Nb on CeCu6, we find a strong dec...
متن کاملHigh-pressure magnetization of the heavy-Fermion system CeRu2Si 2
2014 The low-temperature magnetization of single-crystal CeRu2Si2 has been investigated under hydrostatic pressures up to 6 kbar. The results reveal an extremely rapid decrease of the magnetic susceptibility ~~ (T ~0) for H applied along the c-axis, at a rate of about 201417% per kbar. A strong correlation (~~ (0) Tmax ~ const. ) is found between the pressure-variations of the susceptibility at...
