Abstract
Single-crystal nickel films varying in thickness from 2-40 Å were prepared by epitaxial growth between thicker layers (500 Å) of single-crystal copper (001). Their magnetization was measured as a function of field up to 10 kOe using a dc SQUID magnetometer. The saturation magnetization of these films was determined as a function of Ni thickness at liquid helium temperatures. A decrease in saturation moment from that of bulk nickel was observed for films of thickness less than 18 Å. The apparent Curie temperature also decreases with decreasing thickness for these films. The magnetization at maximum field as a function of temperature does not follow a Brillouin function.This publication has 12 references indexed in Scilit:
