Abstract
Muon spin relaxation measurements are reported on samples of dimethylammonium metal formates containing magnetic divalent nickel, cobalt, manganese, and copper ions. These hybrid organic-inorganic perovskites exhibit weak ferromagnetism and are, apart from the copper system, multiferroics with well-separated magnetic and antiferroelectric transitions. We use muons to follow the sublattice magnetization, observing the effect of the spin reorientation transitions below ${T}_{\text{N}}$ and the criticality approaching ${T}_{\text{N}}$. The multiferroic samples have three-dimensional antiferromagnetic interactions but the copper sample shows quasi-one-dimensional behavior due to its Jahn-Teller distorted structure with a ratio of its interchain and intrachain exchange constants $|{J}^{\ensuremath{'}}/J|\ensuremath{\simeq}0.037$.
