## Abstract An analysis is given of the spectral properties of perturbations of the magnetic bi‐harmonic operator Δ^2^~**A**~ in __L__ ^2^(**R**^__n__^ ), __n__ = 2, 3, 4, where **A** is a magnetic vector potential of Aharonov–Bohm type, and bounds for the number of negative eigenvalues are establi

✦ Synopsis
The main purpose of the present paper is to investigate the semiclassical asymptotics of eigenvalues for the Dirac operator with magnetic fields. In the case of the Schrodinger operator with magnetic field, this problem was recently solved by Matsumoto. We show that the nth positive eigenvalue of the Dirac operator behaves like that of the associated Schrodinger operator via unitary equivalence of ẗheir spectral measures.
