[11p-N402-5] Evaluation of elementary pinning force due to finite long columnar pinning center based on normal-core approximation

〇Tatsunori Okada1, Satoshi Awaji1 (1.IMR, Tohoku Univ.)

Keywords:vortex pinning, elementary pinning force, columnar pin

We evaluated the elementary pinning force due to finite long columnar pinning center via numerical calculation based on the normal-core approximation. In our presentation, we would like to report the angular dependence of the elementary pinning force as a function of (pin radius R, pin length 2H, magnetic field angle θ, effective mass ratio γ, in-plane coherence length ξab).
