Full magnetization process of magnetic nanocluster Mn4, including all its actual multiplets, is theoretically investigated. The formulas needed to determine the exchange constants of cluster Mn4 from experimental data are obtained. It is shown that quantum jumps of magnetization of this nanocluster are in area of megagauss magnetic fields. Remarkable feature of considered nanocluster Mn4 differing it from other multispin molecules is that its exchange spin Hamiltonian supposes exact diagonalization. This provides a reliable basis for comparison of theoretical predictions with experimental data and is important for development of new experimental techniques of high-spin molecule research.
