Electron paramagnetic resonance spectra of Mn 2+ doped in single crystals of strontium tartrate trihydrate grown by a diffusion technique are investigated at room temperature. Mn 2+ enters the lattice substitutionally and is trapped at two magnetically equivalent but crystallographically inequivalent sites. The EPR measurements give the following values for the spin‐Hamiltonian parameters: g x (= g y ) = 1.9781, g z = 2.0012, A x (= A y ) = −94.9 × 10 −4 T, A z = −96.2 × × 10 −4 T, B B 0 2 (= D /3) = +160.9 × 10 −4 T, B 2 2 (= E ) = +101.2 × 10 −4 T, B 0 4= +0.013 × 10 −4 T, and B 2 4= +0.088 × 10 −4 T.
