Abstract :
The anhysteretic behaviour of nickel has been studied by two methods: the conventional field cycling method, and by thermal demagnetization followed by cooling in an applied field. The results show that the field cycling method does not achieve thermal equilibrium, the anhysteretic magnetizations differing by as much as 6% between the two methods. The results are discussed in terms of domain wall pinning
