FIG. 1.

(Color online) MRT model with two interfaces at x = 0 and at x = Δ. This paper concentrates on the case where Regions I and III have a negligible mass density compared with Region II.

(Color online) The profile of the y component of magnetic field B 02y (x) in Region II, 0 < x < Δ, at various δ, indicating different degree of magnetic shear.

(Color online) The normalized MRT growth rate for the case, as a function of kΔ, at various b u, for (a) δ = 104, (b) δ = 1, (c) δ = 0.1, (d) δ = 0.01. The solid lines show the numerical solutions from Eqs. (4)–(6), the dotted lines show the analytical results of Eq. (10), i.e., the zero magnetic shear case.

FIG. 4.

(Color online) The normalized MRT growth rate for the case of and b u = 1, as a function of kΔ, at various δ. The solid lines are from Eqs. (4)–(6), the dotted line is from Eq. (10), i.e., the zero magnetic shear case, and the dashed line indicates the infinite shear case (δ = 0), where MRT does not exist if .

FIG. 5.

(Color online) The normalized MRT growth rate versus kz Δ for the case of and (a) B 01y 2/B 0z 2 = 0.1, (b) B 01y 2/B 0z 2 = 1.0, and (c) B 01y 2/B 0z 2 = 10, at various δ. The solid lines show the numerical solutions from Eqs. (4)–(6), the dotted lines show the analytical results of Eq. (9), for both the zero magnetic shear case [cf. Eq. (10)] and infinite magnetic shear case.
