CEF effects of Ho1−xDyxNi2B2C

Transport properties along c -axis of DyNi 2 B 2 C

“…Since the discovery of the intermetallic quaternary compound superconductors, RNi 2 B 2 C (R = rare-earth elements), many studies have been done on the interplay between superconductivity and magnetism which is one of the most attractive topics in solid state physics and it is now well known that there is a considerable degree of interaction between the conduction electrons and the rare-earth ions in these compounds which brings about the reduction in T C [1][2][3][4][5][6][7][8][9][10]. More detailed studies on single crystals of these compounds containing magnetic rare-earth ions show possess highly anisotropic normal state magnetizations and anisotropic and suppressed superconducting properties, which indicate the existence of a significant interaction between the local magnetic moments and superconducting electrons [5][6][7][8][9][10].…”
