【摘要】 在1.5～300K温度范围内,研究了非品态Y₅Ni₉₅,溅射合金膜的霍尔效应。观察到该材料的正常霍尔系数R_o不随温度改变,R_o=—1.46×10^-12Ω·cm/G;反常霍尔系数R_s值随温度增高而增大,其值从1.5K的—2.2×10^-10变化至300K的—3.3×10^-10Ω·cm/G。利用斜散射和边跳跃机制对此进行了讨论。更多还原

【Abstract】 We have studied the Hall effects of the sputtered amorphous Y5Ni95 films within the temperature range of 1.5-300 K. The ordinary Hall coefficient Ro=-1.46×10-12Ωcm/G and is independent of the temperature. The extraordinary Hall coefficient Rs increases with the increasing temperature, and changes from -2.2×10-10Ωcm/G at 1.5 K up to -3.3×10-10Ω. cm/G at 300 K. Such observed changes of R1 can be explained by the current mechanism of skew scattering and side jump.更多还原
