General Questions and Answers / Regarding the size of the Magnetic Tunnel Junction

« on: March 31, 2011, 15:28 »

What would be the approx. size (in terms of metres) of the Fe and MgO created by the Magnetic Tunnel Junction builder with default parameters of the ATK VNL 2008.10....

General Questions and Answers / Regarding the dimension of Magnetic Tunneling Junction

« on: March 31, 2011, 08:23 »

Can anybody tell me the approx. length, width, height (i.e. A, B, C overall co-ordinate dimension) of the Magnetic Tunneling Junction device with the specifications:

No. of MgO layers -> 2 layers; global repetition along A -> 2; (and the rest the default parameters provided by ATK VNL 2008.10)....

When I simulate my Magnetic Tunnel Junction model, I get the following error:

ATKError: # SpeciesContainer::attributes(Atom const & at) : species not found.


Can anybody tell me the reason for the error...

General Questions and Answers / Re: Converging Magntic Tunneling Junction

Thanks for the reply...

I have 3 Gb RAM.. When I create Magnetic Tunneling Junction with specifications: '4' layers Fe - both right & left electrodes, '2' layers MgO - non-magnetic spacer, and global repetition along A - '2', the system converges. When I plot I-V curve, I get current in the range of micro-ampere..

Is it possible 2 get current in mill-ampere range...

General Questions and Answers / Converging Magntic Tunneling Junction

« on: February 17, 2011, 09:20 »

Hi,
I tried simulating Magnetic Tunneling Junction with the specifications: Fe '6' layers for both right and left electrodes, MgO '2' layers and Global repetition along A as '2' and I get the following error..

Traceback (most recent call last):
  File "c:/users/vinod/appdata/local/temp/tmpjdzrah.nl", line 601, in ?
    runtime_parameters = runtime_parameters
ATKError: bad allocation
Terminated Abnormally

I've attached both the scripts and log output here... Can somebody please help me to rectify this problem...
Can I increase the global repetition more than '2'...
