Electromagnetic strength functions are esential observables to study the formation and decay of atomic nuclei. They also play an important role in, e.g., nuclear astrophysics.
Magnetic dipole strength functions, B(M1), are particularly challenging to compute within one of the most widely used methods in nuclear structure calculations, namely, the projected generator coordinate method (PGCM). In even-even nuclei, where the B(M1) strength functions are computed from the 1+ excited states to the 0+ ground state, the most difficult part is the obtention of these 1+ states. 
In this seminar I will present the first PGCM calculations of B(M1) strength functions in light even-even nuclei performed with the newly developed TAURUS suite. The results will be benchmarked against exact Shell Model calculations.
