Gv. Gorr, A LINEAR INVARIANT RELATION IN THE PROBLEM OF THE MOTION OF A GYROSTAT IN A MAGNETIC-FIELD, Journal of applied mathematics and mechanics, 61(4), 1997, pp. 549-552
The method of invariant relations is used to determine conditions for
the existence of a linear invariant relation of the Hess type in a pro
blem of the motion of a heavy rigid body in a magnetic field, taking t
he Barnett-London effect into account A special case is indicated in w
hich the reduced system of differential equations of motion has an add
itional first integral. (C) 1997 Elsevier Science Ltd. All rights rese
