Inverse Faraday effect

The inverse Faraday effect is the effect opposite to the Faraday effect. A static magnetization M → ( 0 ) {displaystyle {vec {M}}(0)} is induced by an external oscillating electrical field with the frequency ω {displaystyle omega } , which can be achieved with a high intensity laser pulse for example. The induced magnetization is proportional to the vector product of E → {displaystyle {vec {E}}} and E → ∗ {displaystyle {vec {E}}^{*}} : The inverse Faraday effect is the effect opposite to the Faraday effect. A static magnetization M → ( 0 ) {displaystyle {vec {M}}(0)} is induced by an external oscillating electrical field with the frequency ω {displaystyle omega } , which can be achieved with a high intensity laser pulse for example. The induced magnetization is proportional to the vector product of E → {displaystyle {vec {E}}} and E → ∗ {displaystyle {vec {E}}^{*}} : M → ( 0 ) ∝ [ E → ( ω ) × E → ∗ ( ω ) ] {displaystyle {vec {M}}(0)propto } From this equation we see that the circularly polarized light with the frequency ω {displaystyle omega } should induce a magnetization along the wave vector k → {displaystyle {vec {k}}} . Because E → {displaystyle {vec {E}}} is in the vector product, left- and right-handed polarization waves should induce magnetization of opposite signs.
