在高达52T的脉冲磁场中测量了重费米子反铁磁体YbPtIn(TN1=3.4K,TN2=1.4K)的磁化强度。在Tn2以下,观察到了H⊥c的多阶变磁跳跃,这可能是由于存在一种起源于受阻磁相互作用的复杂磁结构。在0.95 Gpa的高压下,H-⊥-c在7K和0.1T以下出现新相。
Magnetization of the heavy fermion antiferromagnet YbPtIn (TN 1=3.4 K , TN 2=1.4 K ) has been measured in pulsed magnetic field up to 52 T . Below TN2, multistep metamagnetic jumps are observed for H⊥c, which may be attributed to an existence of a complex magnetic structure originating from a frustrated magnetic interaction. A new phase appears below 7 K and 0.1 T for H⊥c by applying high pressure of 0.95 GPa .
