摘要: The transverse magnetoresistivity ρ H , Hall coefficient R and specific heat C for ∥ a below 10 kOe the moderate heavy-fermion ferromagnet YbPtGe with Curie-temperature T =5.4 K are reported. It is observed that ( ) values currents along three crystallographic axes markedly decrease 30 increasing applied magnetic field up to 90 kOe. Below at low fields show peak structures b shoulder c positions of which correspond those shoulders in dependence magnetization. sharp due transition decays shifts low-temperature side 3 – phase diagram proposed from measurements. In addition, I increases value close expected carrier concentration 1 hole/f.u. decreasing temperature 300 K,...
