   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanomagnets; magnetic deflagration; front instability; Zeeman energy; magnetic instability; magnetic detonation; weak detonation; Physics Of Matter; materiefysik;

   Sammanfattning : In this thesis we cover the dynamics of the macro magnetic transformations (spin avalanches) in crystals of molecular nanomagnets, also known as magnetic deflagration and detonation.Taking a single-molecule Hamiltonian, we calculate the dependence of Zeeman energy and the activation energy as a function of an external magnetic field at different angles relative to the easy axis of the crystal.
