Heavy fermions in high magnetic fields Project supported by the National Natural Science Foundation of China (Grant No. U1632275), the National Key R&D Program of China (Grant Nos. 2017YFA0303100 and 2016YFA0300202), and the Science Challenge Project of China (Grant No. TZ2016004). |
(a) Magnetic field dependence of the heat capacity of CeRhIn5 at various temperatures when the field is along the c-axis. (b) Field–temperature phase diagram of CeRhIn5 for fields along the a- and c-axes. AF and P denote antiferromagnetism and paramagnetism, respectively, while the subscripts mark a small (S) or large (L) Fermi surface. Reproduced from Jiao et al., Ref. [ |
