  We study non-relativistic supersymmetric field theories in diverse
dimensions. The theories consist of scalars and fermions and possess two, four
or eight real supercharges. We analyze their spontaneous supersymmetry breaking
structure and calculate the gapless spectrum. We calculate the perturbative
quantum corrections at the supersymmetric vacua and show that while
supersymmetry is preserved, scale invariance is broken and the theories are IR
free.
