title: Linearized magnetoacoustic sensor of angular displacements.
abstract: The design of a quasilinear sensor of angular displacements based on acoustic resonance in an antiferromagnetic single crystal was considered. The frequency versus angle dependence of a crystalline alpha-Fe(2)O(3) acoustic resonator placed in a rotating inhomogeneous bias field was studied experimentally. A linearization of this dependence was obtained, respectively, for frequency and angular operation ranges equal to Deltaf/f(max)=14% and Deltatheta=140.
