How to collect each magnetic moment component of each layer/Region

[Apukumar jana]

Dear All,

I am doing a simulation of two layers/regions.

I want to use a term like: Crossproduct of mx of upper layer and my component of down layer.

I will be grateful if you please let me know how to save each magnetic component of each layer.

Thanks and regards

Apu

Hi,

Based on your wording, I assume you want to use this for a custom field term, not just save them? If you just want to save them, you can do something like save( m.Comp(0).region(1) ).

For a custom field term using a crossproduct, you could do something like:


u1:=ConstVector(1,0,0)
u2:=ConstVector(0,1,0)

//term applied to upper layer
mx_upper_appliedtoupper:=   Mul(Dot(m,u1),u1)
my_lower_appliedtoupper:= Mul(Dot( Shifted(m,0,0,-1),shifted(u2,0,0,-1)),u2)
upperterm:= Cross(mx_upper_appliedtoupper ,my_lower_appliedtoupper)
uppertermMasked:=Masked(upperterm, layer(0))

//term applied to lower layer
mx_upper_appliedtolower:= Mul(Dot(Shifted(m,0,0,1),Shifted(u1,0,0,1)),u1)
my_lower_appliedtolower:= Mul(Dot(m,u2),u2) 
lowerterm:=  Cross(mx_upper_appliedtolower ,my_lower_appliedtolower)
lowertermMasked:= Masked(lowerterm,layer(1))

AddFieldTerm(uppertermMasked )
AddFieldTerm(lowertermMasked )

Best,
