We investigated the influence of feeding rate on the behavior of the rose anemone Urticina piscivora. We predicted that anemones would travel less and be less willing to detach from the substrate in response to contact with a predator (Dermasterias i

The 'plate domain' structure in an Fe(5% Si) bar crystal with Neel orientation (bar axis (110); side faces (110) and (001)) is scanned by perpendicular transmission with polarised neutrons ( lambda >or=0.4 nm) and subsequent three-dimensional polaris

The domain structure was investigated as a function of the frequency f of an alternating circular idealization field. The results show that only below a critical value f c the domain structure is independent of the frequency. The critical frequency f

The influence of different thermomagnetic preparatory treatments of a 5% Si-Fe single crystal with Neel orientation on the behaviour of the magnetic domain structure was investigated by means of the Kerr magneto-optic effect. The crystal was cooled d

For amorphous Co66Fe4Mo1.5Si16.5B10.5 alloys different magnetic states (flat loop, round loop, square loop) are produced by means of the induced anisotropy. The best dynamic properties (highest permeability up to 850 000 for 50 Hz and lowest losses)

The domain structure was investigated as a function of temperature and field up to the Curie-point. For both materials the plate- and wedge-shaped domains strongly depend on the thermal treatment, the Bloch walls being movable or immovable and the do

The equilibrium main and closure domain structure at room temperature is fully analysed as function of field. The temperature dependence of the equilibrium domain width is found reversible above 500°C, below it depends strongly on the prior treatmen
