For a broad range of fourfold, uniaxial, and unidirectional anisotropies, our results illustrate that the exchange bias can grow significantly for a sample rotation off the cooling field direction, while for other combinations of anisotropies, a positive exchange bias can be found near or even in the cooling field direction. These findings allow identification of anisotropies based on superconducting quantum interference device or magneto-optical Kerr effect measurements as well as tailoring desired angular dependencies for magnetoelectronic applications.
