abstract = "Magnetic field generation in three-dimensional RayleighB{\'e}nard
convection of an electrically conducting fluid is studied
numerically by fixing the Prandtl number at P=0.3 and varying the
Rayleigh number (Ra) as a control parameter. A recently reported
route to hyperchaos involving quasiperiodic regimes, crises and
chaotic intermittent attractors is followed, and the critical
magnetic Prandtl number (Pmc) for dynamo action is determined as a
function of Ra. A mechanism for the onset of intermittency in the
magnetic energy is described, the most beneficial convective
regimes for dynamo action in this transition to weak turbulence
are identified, and the impact of intermittency on the dependence
of Pmc on Ra is discussed.",
