Two of the most important parameters in magnetic measurements are the coerc
ive field, H-c, and the remanent coercive field, H-r. In this paper we will
look at these parameters in relation to vector measurements taken at an an
gle with the (mean) anisotropy direction. We will show that the definition
and interpretation of these parameters should be reconsidered for angular m
easurements. (C) 1999 Elsevier Science B.V. All rights reserved.
