Magnetic phases in Gd1−xYx thin films

Abstract High-resolution electrical resistivity ( ρ ) and its temperature derivative (d ρ ⧸d T ), magnetization (M) and its temperature derivative (d M /d T ) and magnetoresistance (Δ ρ ⧸ ρ ) and its field derivative (d(Δ ρ ⧸ ρ )⧸d H ) measurements have been done in a thin film of Gd 67 Y 33 prepared by the MBE technique. All the derivatives were obtained using numerical differentiation of our high-resolution data. The sample exhibits properties similar to those that are present in bulk samples but new insight is obtained.
