Abstract: A vibratory or spring element. The element is formed from a paramagnetic alloy having a temperature coefficient of the moduli of elasticity between -10.sup..sup.-4 per centigrade and +10.sup..sup.-4 per centigrade and having the following further characteristics:A. a magnetic atomic susceptibility .chi. of greater than 10.sup..sup.-4 emu/g-atom at room temperature, corresponding to a specific heat (electron heat) of greater than 10.sup..sup.-3 cal/g-atom(.degree.K).sup.2at low temperature;B. a non-positive temperature coefficient dN (E.sub.F)/dTof the effective density of states exhibited in a non-positive temperature coefficient d .chi./d T of the magnetic susceptibility.
