Presented are magnetization measurements on a crystal of Fe8 single-molecule magnets using a Hall probe magnetometer. Irradiation with microwaves at frequencies of 92 and 110-120 GHz leads to the observation of electron paramagnetic resonance (EPR) detected via magnetization measurements. A quantitative analysis of the results are introduced by means of the spin temperature. It is shown that pulsed microwave experiments allow a better control over the spin excitation.
